It's the end of an era for MythBusters: Kari Byron, Tory Belleci and Grant Imahara are leaving the series. Adam Savage and Jamie Hyneman announced the fan-favorites would depart the show at the end of the Thursday, Aug. 21 episode of the hit Discovery program.

Kari and Grant took to Twitter to share their feelings with fans after the announcement.

"I guess you guys are finding out the news right about now. After a decade of the MythBusters, we are no longer with the show," Kari said in a series of tweets. "Thank you to all the fans who have supported us. The show is taking a new direction. It was an amazing run. I learned so much about myself and the world. I love you all @MythBusters. I am sad for an ending but there will be exciting new adventures for us."
